Installation of fiber optic online temperature measurement system for box transformer switchgear

Fluorescent fiber optic temperature measurement system can be applied in power systems, and the commonly used sensor in power equipment is the fluorescent fiber optic temperature measurement sensor.

1. Box mounted fluorescent fiber optic temperature measurement system

The fiber optic temperature online monitoring system for box transformers can directly monitor the temperature of the low-voltage side circuit breaker contacts, cable joints, and other parts of the box transformer. By using a fluorescent fiber optic temperature measurement probe, the temperature of the low-voltage side circuit breaker contacts and cable joints of the box transformer can be sensed, and the operation of the box transformer can be intuitively monitored and evaluated. Overheating problems at the contacts or joints can be detected in advance to avoid adverse effects on the insulation and service life of the box transformer.

The fiber optic temperature online monitoring system for box transformers generally consists of fluorescent fiber optic temperature sensors, fiber optic temperature sensors (display modules), optical cables, etc. Each box transformer has no less than 6 temperature measurement points, of which the temporary ones are the contact temperature of the low-voltage side circuit breaker (3 points) and the cable joint temperature (3 points), and the final measurement points are determined by the project unit. Real time online monitoring and fault alarm can be achieved. In addition to displaying alarm information on site, it can also be transmitted to the monitoring background through RS485 interface and achieve remote monitoring. The temperature measurement system device must pass the type test integrated with the box transformer and provide relevant inspection reports.

2. Fluorescent fiber optic temperature measurement system for switchgear

The fluorescent fiber optic temperature measurement system for switchgear can be applied to high-voltage switchgear to measure the temperature of hot spots such as contacts, busbars, and cable joints that are prone to temperature rise through contact type temperature sensing probes. The fiber optic itself is resistant to high voltage, insulation, interference, has a long service life, and is stable and accurate in temperature measurement. A fiber optic temperature measurement host can connect multiple fiber optic sensors to monitor and display temperature for multiple hotspots simultaneously. Provide installation guidance solutions for fiber optic temperature measurement systems.

3. Fluorescent fiber optic temperature measurement for transformers

The most accurate method for internal heat dissipation in transformers is to use a fiber optic temperature measurement system for measurement. The winding fiber optic temperature measurement system can directly achieve distributed measurement of transformer winding temperature, with the characteristics of accurate measurement, low interference, and long service life. The fiber optic sensor is installed at the end of the winding, and real-time online monitoring of the fiber optic temperature at the end of the winding can effectively solve the installation problem of the fiber optic sensor and timely detect internal heat dissipation faults during abnormal operation of the transformer. This maximizes the prevention of unexpected accidents, reduces operation and maintenance costs, and reduces the loss of transformer life.
